Troubleshooting

1) General

The program writes information to a log file, which might contain helpful information. It is located in the cache directory, usually in ~/.cache/cpdctrl-gui.

2) The Arduino/LEDD1B does not work

  1. Make sure the Thorlabs LED is plugged in, turned on (turn the dial to a non-zero value) and that the switch is in the TRIGer position
  2. Reset the Arduino by pressing the white button on the top and restart the program
  3. Unplug and replug the Arduino and restart the program
  4. Re-upload the code (see section "Technical Information/Arduino Code")
